Sugar substitutes do not increase cravings or weight in yearlong trials

A narrative review recently published in the journal *Nutrients* consolidates evidence from three major European research consortia—SWEET, SWITCH, and Sweet Tooth—to examine long‑standing questions about the impact of non‑nutritive sweeteners (NNSs) and sweet‑tasting foods on body weight, metabolic health, and taste preferences. The review draws on large, longitudinal datasets generated by these consortia, which collectively encompass diverse populations across several European countries.

The authors systematically synthesize findings that investigate whether regular consumption of NNSs and other sweet‑tasting foods contributes to changes in body mass index, glycaemic control, lipid profiles, and overall metabolic risk. They also review evidence on how repeated exposure to sweet flavours may alter individual taste preferences and dietary choices over time. By integrating data from SWEET, SWITCH, and Sweet Tooth, the review offers a comprehensive overview of current knowledge and highlights methodological strengths and gaps across the studies.

Overall, the article provides a balanced appraisal of the existing literature, underscoring the need for further research to clarify causal relationships and inform dietary guidelines. The synthesis serves as a reference point for policymakers, clinicians, and researchers interested in the long‑term health effects of sweet‑tasting foods and NNSs in European populations.
